A delete-vector scan also removes surviving null-valued rows · case 03

A delete-vector scan also removes surviving null-valued rows.

Case contract

Scan fragments [file-id,base-row-position,values] applying position-delete pairs [file-id,absolute-row-position]. Deletions are file-scoped and use physical positions before filtering. Return [file-id,absolute-position,value] for surviving rows, including null values.

Why this case matters

A bounded deterministic data engine model makes representation and changelog faults reproducible.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
surviving null	`[["a", 1, 3]]`	`[["a", 0, null], ["a", 1, 3]]`	Failed
